Patent JP-S6448465-A (JP)
Title: Semiconductor device
Inventor: OKADA SHIGEMI
IPC: H01L29/78
Filed: 1987-08-19
Abstract: PURPOSE:To make heterogeneous areas to be non-operating areas while the area other than the heterogeneous areas being made to operate uniformly, by making a diffusion area to be of a square shape and by forming the overlapping sections of a second diffusion area. CONSTITUTION:A first diffusion area 3 with a square shape is finally treated by a thermal diffusion, but the corner sections thereof become of a light impurity concentration owing to the square shape thereof. That is, because the impurity concentration of the corner sections is lower than that of the other area in the area 3, the corner sections become such operating areas that operate ununiformly. And, a P<+> type second diffusion area 6 is so formed as to overlap with each of the corner sections. As a result, the conductivity type of the corner sections is converted from N<-> type to P<+> type, which makes the corner sections to be non-operating areas. Therefore, the area other than the corner sections is of homogeneous impurity concentration, which enables said area to operate uniformly.

Title: Video disc reproducing device
Inventor: MARUTA KEIJI
IPC: G11B27/34
Filed: 1985-09-18
Abstract: PURPOSE:To attain a residual display by detecting an address signal of the last frame of a video disc or an address signal delimiting a chapter and operating the address signal during the reproduction and the detected address signal to obtain the residual amount. CONSTITUTION:When the reproduction is designated, a feeding motor 4 is controlled by a thread servo signal in the pre-stage starting the reproduction and an optical pickup 3 is displaced to the outermost track. The address signal of the last frame of the outermost track is read by the optical pickup 3 and fed to a control section 7 via a signal processing circuit 6. Audio and video information is read from the video disc 1, the reproducing signal is fed to the signal processing circuit 6 and the audio signal and the video signal are extracted at an output terminal 6a. The address signal representing the frame address during reproduction is fed from the signal processing circuit 6 to the control section 7 and the frame address during reproduction is subtracted from the last frame address, and the remaining frame number, that is, the residual amount is calculated. Thus, the residual display is attained in a display section.

Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To reduce burden on a waist by providing a waist pad with at least one end thereof linked to the front of a kitchen cabinet for receiving the waist of a worker to support the waist. SOLUTION: A waist pad 2a is so arranged that at least one end thereof is linked to the front of a kitchen cabinet 1. When the belt type waist pad 2a is set, it is allowed to be slightly slackened during the unuse period to keep a proper interval between the worker and the front of the cabinet 1 even when the worker moves to any position in the front of the cabinet 1. A winding mechanism is provided at one end of the front of the kitchen cabinet 1 from which the waist pad 2a is extended to wind the waist pad 2a inward so that the waist pad can be housed into the kitchen cabinet 1 during the unuse period. The worker puts the waist pad on his waist on use so that his weight is also kept on the waist pad when working by leaning against it. This reduces burden on the waist thereby preventing the worker from suffering lumbago or the like.

IPC: B64G1/44
Filed: 1990-08-03
Abstract: PURPOSE:To effectively use excess power of a solar cell circuit and to weaker the influence to the cell characteristics by selectively connecting a constant- current controller for outputting a constant current from a main bus to supply it to a battery bus, in parallel with a charging array in response to the requested power of a load. CONSTITUTION:A constant-current controller 11 connected in parallel with a charging array 7 operates in the same way as the array 7, and a constant current output is supplied from a solar cell circuit 1 to a battery bus 10. A plurality of the controllers 11 are connected in parallel, and connection/ disconnection is controlled by a relay switch 12. A heavy load might be connected in a satellite. In this case, the surplus power is used through the controller 11. When a heavy load is not applied, the controller 11 is opened, and the power is consumed in a shunt unit 2. Thus, the surplus power of the circuit 1 can be effectively used. Thus, battery discharge power at the time of sunshine is reduced to weaker the influence to the cell characteristics.

Title: Image recording apparatus and image recording method
Inventor: KITAMURA SHIGEHIRO
IPC: H04N1/403
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce the banding irregularity and improve the concentration reproductivity of an gradation image by having a common multiple of the unit pixel number of a pattern dither as the laser beam channel number. SOLUTION: An image recording apparatus 1 drives a multi-head 60 by a laser driving part 50 for recording a two-dimensional image. In changing concentration gradation data to binary data accordingly, mask data provided with a threshold value are used. In this embodiment, since the basic pattern number of the threshold value mask of the dot array and the laser beam array unit are same, the banding irregularity can be reduced by control of the laser beam light amount per multi-channel of the multi-laser head 60 and matching the boundaries of sub-scanning. Furthermore, since the laser beam channel number is a common multiple of the unit pixel number of the pattern dither, the banding irregularity can be reduced by exposing a predetermined position of the dither pattern.

IPC: H04N5/225
Filed: 1983-11-02
Abstract: PURPOSE:To prevent generation of uncomfortable sound by inserting the head part of the pin of a cam barrel into the hollow part formed in the stem part of a stopper member provided to a zooming ring, loading a spring, etc. into the spacing between the head part of the pin and the stem part and disposing a cushion material in the part which contact with the long groove end of the stem part and a macro plate. CONSTITUTION:The head part of the pin 4' of a cam barrel 3 is inserted into the hollow part formed to the stem part 8b of a stopper member 8. One end of a stem part 8b is projected outward at all times by the energizing force of a spring 9' loaded in the hollow part. A cushion material 5' is wound on the part of the stem part 8b which contacts with the long groove ends 11, 12 and this part slides in the long groove 6a'. Therefore if the zooming ring 7 is rotated in a tele direction, the material 5' and the end 11 contact with each other and when said ring is rotated in a wide direction, said material contacts with the end of a macro plate 10. When the fine diameter part of the stem part 8b is inserted into a notch 10a by pushing said part, the ring 7 can be further rotated up to the macro end and the material 5' contacts with the long groove end 12. Since the cushion material is always intervened in the contact part in the above-mentioned way, generation of uncomfortable noise is obviated and since just one groove of the lens barrel is required, the reliability interms of strength is improved.

Title: High frequency electron gun
Inventor: NISHIHARA SUSUMU
IPC: H01J49/08
Filed: 1990-08-04
Abstract: PURPOSE:To simplify a device as well as to make operations simpler with the effect of activities enhanced by controlling both electrons pulled out by a positive electric field and microwaves in phase so as to be put in the phase of a negative electric field, and thereby activating a cathode. CONSTITUTION:A high frequency electron gun 1 allows a microwave generating device 8 to generate microwaves within a high frequency cavity 6 by means of signals from a reference signal generator 10. In a phase shifting device 11, laser beams which are locked in mode by a laser beam generating device 9, are generated to the timing where these microwaves shall be in an accelerating phase for photo electrons to be generated later on. These laser beams are hit against a cathode 2 so that photo electrons are thereby generated, and these photo electrons are loaded on the accelerating phase of microwaves generated within the high frequency cavity 6 by the device 8 so as to be accelerated. When the cathode 2 is activated, generated electrons are pulled out by a positive electric field so as to be accelerated. These electrons go into the phase of a negative electric field because of change with time, they are decelerated, they are suspended, and they are finally accelerated to the reverse direction, so that electrons imparted with kinetic energy are hit against atoms in the cathode 2 so that the cathode 2 is thereby activated.
